My version of a 2x3, 1.27mm pitch POGO pin adapter. Inspired by PogoProg Model D that I’ve used, but is no longer in stock.

Materials

• 0.68mm diameter POGO pins; P50-E2 or P50-B1
• 2.54mm pitch 2x3 header; male, right angle or male 2x3 socket

Assembly Tips

• Place the PCB on top of something with the POGO pin side hanging over the edge.
• Insert POGO pins, using the height of the object(s) holding the PCB up to set the high of the POGO pins.
• May help to insert and solder two pins at a time.
• Use lots of flux to help the solder flow.
• Excess solder can be removed with a solder sucker or by wicking small amounts of solder onto a clean iron tip, cleaning the tip, then repeating several times.
• Wash POGO pins thoroughly with Isopropyl Alcohol (IPA) after assembly to remove any flux inside the pins that might cause them to become stiff later on.
